Plaub hom pa phem yuav tsum tau kho: HC , CO , NOx thiab PM . Piv nrog cov tsheb roj av, cov pa phem PM nrog cov pa roj carbon ntau yuav tsum tau tswj. Qhov cua kub ntawm diesel forklifts qis dua li ntawm cov tshuab diesel uas twb muaj lawm. Qhov cua kub ntawm lub muffler feem ntau qis dua 200 degrees rau lub sijhawm ntev. Qhov ntsuas kub qis ua rau peb qhov teeb meem: nyuaj hauv NOx kev kho mob, nyuaj rau PM purification, thiab blockage ntawm DPF thiab catalyst sulfate. Diesel forklifts muaj qhov nyuaj ntawm cov roj diesel thiab tsis yooj yim rau kev tswj hwm raws li kev tsheb. Ntau lub tsheb siv cov ntsiab lus sulfur siab. Diesel forklifts feem ntau yog kev txhim kho ntawm cov tshuab ua liaj ua teb 490 cav tshuab ntawm lub xyoo pua xeem. Qhov teeb meem ntawm cov roj hlawv tseem yog ib qho tshwm sim, thiab cov roj muaj qhov cuam tshuam tsis zoo rau cov pa tawm ntawm DPF. Tus neeg sawv cev txo qis HC thiab CO yog qhov tsawg dhau, uas tsis tsim nyog rau kev txo qis ntawm NOx, thiab nws tsis tsim nyog rau qhov nce ntawm cov pa kub. Qhov txo qis ntawm NOx yuav tsum muaj tus neeg sawv cev txo qis ntxiv. Cov pa ntau dhau hauv cov pa tso pa tuaj yeem ua tiav. 6 - 15 feem pua, NOx txo qhov nyuaj.
